Ik get the next warning (i have a aiContactSafeForm in a K2 item):

Warning: file_exists() [function.file-exists]: open_basedir restriction in effect. File(public_html/index.php/component/k2/item/index.php) is not within the allowed path(s): (/home/strijkse/:/tmp/) in /public_html/includes/router.php on line 57

Warning: Cannot modify header information - headers already sent by (output started at /public_html/includes/router.php:57) in /public_html/components/com_aicontactsafe/models/message.php on line 1093

This is the link: www.strijkservices-bestellen.nl/index.php/component/k2/item/14-strijkservices-hs-in-breda-prinsenbeek-bavel-en-teteringen

How can i fix it?
